Pump and engine assembly

A skid mounted engine and pump assembly comprising:

• skid means comprising a support base;
• first and second engine means mounted on said skid in side-by-side relation, each of said engine means defining a rotary output shaft;
• first and second piston displacement pumps mounted in side-by-side relation on said skid means and defining fluid ends each facing in the same direction, each of said pumps having a pump housing, a bull gear being supported for rotation within each said housing and being interconnected in driving relation with a crank shaft and reciprocating piston system;
• first and second drive shafts being rotatably supported in spaced, generally parallel relation by said housing of said first pump;
• pinion gear means being provided on said first drive shaft and being in gear meshing relation with said bull gear of said first pump;
• said second drive shaft having extremities projecting from opposed sides of said pump housing of said first pump, one of said extremities being coupled to said output shaft of said second engine means;
• a drive shaft being rotatably supported by said housing of said second pump;
• pinion gear means being provided on said drive shaft of said second pump and being in meshing relation with said bull gear of said second pump;
• means coupling the other of said extremities of said second drive shaft of said first pump to said drive shaft of said second pump;
• and
• means coupling said first drive shaft to said output shaft of said first engine means.

A pump mechanism adapted to be driven by power source means through a rotary power output shaft of said power source means for pumping of a fluid medium, said pump mechanism comprising:

• a pump housing;
• a primary gear being supported for rotation within said housing and defining an outer gear periphery, said primary gear being operatively interconnected with fluid pumping means of said pump;
• at least two drive shaft receptacles being formed in said housing along respective centerlines substantially equally spaced relative to said outer gear periphery of said primary gear;
• first and second drive shafts and bearing means being supported by said drive shaft receptacles, and
• secondary gear means being provided on said first drive shaft means and having gear meshing engagement with said outer gear periphery of said primary gear, said first drive shaft means adapted to be coupled for rotation by said power source means;
• and
• each extremity of said second drive shaft projecting from said housing, one of said extremities of said second drive shaft adapted for driving interconnection with said power source means, the opposite extremity of said second drive shaft adapted to be coupled to the drive shaft of an adjacent pump, thus adapting said adjacent pump to be driven through said first pump by said power source means.
